摘要
垫片的蠕变-应力松弛特性对螺栓法兰密封连接系统的可靠性有显著的影响。作者按照GB/T19066.3的实验条件对标准规格为D65.5mm×50.5mm×2.5mm 3种不同几何尺寸的金属(06Cr19Ni10+柔性石墨)波齿复合垫片进行蠕变-应力松弛实验研究,从而找出应力松弛特性影响因素及其规律,为工程实践提供科学指导。
The study showed that stress relaxation characteristic of gaskets has remarkable influence on reliability of bolt-flange linking system.The paper was in according to GB/T19066.3 test conditions to be testing for flexible graphite corrugated metal gaskets of standard D 65.5 mm×50.5 mm×2.5 mm,three various circular arc radius,wave gear distance and gear quantity,and found out the affection factor and regular on stress relaxation characteristic,to provide scientific basis for engineering practice.
